Boulder Crevices Brimming with Pebbles

This image provides a detailed view of a large boulder that is located northwest of sample site Nightingale on asteroid Bennu. Fine-grained material is visible in the boulder’s crevices and at its base. The image was taken by the PolyCam camera on NASA’s OSIRIS-REx spacecraft on March 3 from a distance of 0.2 miles (0.3 km). The field of view is 11 ft (3.5 m). For reference, many of the pebbles resting on the boulder’s surface are between 1 and 2 inches (2.6 and 5 cm) wide, or range from the size of a cherry tomato to the size of a lime. The image was obtained during the mission’s Reconnaissance C phase. When it was taken, the spacecraft was over the northern hemisphere, pointing PolyCam north and to the west.
